It’s that time of the year again when Australia’s Clean Energy Regulator releases the updated data on Australia’s top solar postcodes – the rooftop PV hot-spots of each state and territory that are leading the uptake of residential and commercial solar systems sized between 0-100kW.

As we reported here, Australia’s rooftop solar installations continued on their record-breaking way in October, with 158MW of PV systems installed across the month – 15 per cent more than in the previous record month in August.

According to solar analyst SunWiz, the month saw Victoria join NSW to become the one of the hottest markets in the country, while Western Australia surged beyond the 1GW mark.

But which are the top solar postcodes of Australia?

This year there are some new names that have made the ranks, according to the CER, which has tallied small-scale solar installations for the June to September period.
